In this particular case, and by that I mean "for this particular input only", you could match it with:

>>([^<]+)<<

Make sure that whatever implementation you are using supports matching in the middle of a string, rather than just at the beginning. The parentheses represent the capture group.

If you need to get the test that is NOT in that group, you could use:

([^>]+>>)[^<]+(<<[.]+)

Now, the two capture groups have the text you want.

Edit: since you're using Java, make sure you use Matcher.find() rather than Matcher.matches() in the first case.

might be more flexible to just get rid of the comments enclosed in <<.*>>

In perl:

$string =~ s/<<.*?>>//g
